Method and apparatus for producing varying-geometry mirrors to be used in conventional and free-electron lasers.

摘要

A method for producing varying-geometry mirrors consisting in subjecting a thin sheet or grid to an electromagnetic force field of controlled settings so as to cause the treated member to deform according to the desired curved shape. The apparatus for actuating such method includes a pair of permanent magnets between which the reflecting mirror is placed and locked to supports associated to a micrometer shift device, and means for adjusting the gap between such magnets and the interposed member. <IMAGE>
